McKenzie Rollins began riding at the age of five at the Stoneleigh- Burnham School in Greenfield, Massachusetts. She graduated from Stoneleigh where she was very active on her high school IEA team and Interscholastic Dressage Team. She then attended the University of Vermont, where she graduated with a BFA in Studio Arts and a Minor in Film Theory. She also studied Equine Management & Equine Training Techniques and rode on the Equestrian Team, which is also where she began her teaching career under the tutelage of Madeline Austin.
Upon graduation, McKenzie worked briefly in New York City in fashion and photography, yet still rode whenever possible and taught periodically at the Stoneleigh-Burnham School. She then found herself employed by The Ethel Walker School in 2007 and was very involved in many aspects of the Equestrian Program as an instructor, trainer, adviser to Middle School students, manager & instructor of the IEA team (which she brought to numerous National Championships) & manager/trainer of the Eventing program and The Summer Riding Experience.
McKenzie organized the USEA-recognized Horse Trials held at Ethel Walker each fall, and is an active competitor on the Eventing circuit. She also led numerous trips to North and South Carolina with her Eventing students.
